17.5 Current Value Update
The current value update function is used to set the "current value after conversion of unit
system" saved in the positioning memory to any value.
• Set the value as the current value via the user program in the current value update
coordinates area (positioning memory area no.0/Address HC8-HD7) of the positioning
memory.
• When the bit of the target axis of the current value update question flag area (positioning
memory area no.0/Address HC0) is set to ON, the "current value after conversion of unit
system" of the information area of each axis (positioning memory area no.1/Address H3E-
H3F) will be changed to the designated current value.
Sample program
An example of presetting any value K100000 in the positioning memory area to update the
current value after conversion of unit system of axis-1 is given below. In the first line of the
program, read the current value after conversion of unit system of axis-1 to the data registers
DT0-DT1 for monitoring.
